PULP GATHERING AND TBANSFERRING- DEVICE.

Application filed January 23, 1915.

To all whom it may concern:

Be it known that we, Ana-Hon J Honor: and Hum: B. RUGGLES, citizens of the United States of America, residing at Pasadena, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Pulp Gathering and Transferring Devices, of which the following is a specification.

This invention has relation to certain new and useful improvements in pulp gathering and transferring devices and has for its primary object, the provision of new and improved mechanism for gathering pulp from a pulp containing tank and transferring the same to opposite sides of forms or formersections traveling through said tank.

Another object of the invention resides in the provision of a pulp gathering and transferring de ice which will be of such construction that the pulp gathering andtransferring wheels will be arranged in vertical series and to opposite sides of the moving forms or former-sections, with the wheels of each series positioned on an incline correspondin g to the spiral movement of the forms or former-sections.

The invention has for another object, the provision of a device of this character which will be of such construction and operation that it may if desired be readily substituted for the p imary compressing and squeezing Number 741 or any other analogous ma-,

chine, and employed as a primary compress ing device to partially compress moving forms or former-sections or employed in connection with any part or parts of any machine or machines of the character disclosed in the'referred to application Serial Number 741 or of any other character with which the present device will cooperate.

A further object of the invention resides in the provision of a pulp gathering and transferring device of the above stated charactor in which each wheel of each and every series will be mounted for rotation upon a separate inclined swinging plate, during up ward spiral movement of the forms or former-sections between said series, each plate being resiliently connected with the corresponding plate of the adjacent series to cause the wheels of the variousseries to gather and transfer to the forms or formen Specification of Letters Patent.

sections equal amounts of pulp from theparts of which will be arranged around the spirally movable connected forms or formersections in such manner that operation of the mechanism will be governed by the movement of the forms or former-sections, and the pulp gathered by the wheels may be readily transferred to said forms or formersections and compressed upon the latter, suitable means being carried by the wheel supporting plates to prevent the pulp from adhering to the portions of said wheels opposite the forms or former-sections.

\Vith these and other objects in view, our invention consists in the novel construction, combination and arrangement of parts as will be hereinafter more in detail described and the asserted novelty specifically pointed out in the claims.

In the accompanying drawings which clearly and fully illustrate our invention 2- Figure 1 represents a side elevation, with parts in section and parts broken away;

Fig. 2 is a top plan view, with the inclined plate supporting shafts in section;

Fig. 3 is a top plan view of the device in operation, showing the manner in which the pulp is gathered from the tank by the wheels and transferred by the latter to the moving forms or formensections and compressed around the same;

Fig. d is a transverse vertical section through the lower portion of the device, as shown in Fig. 3, the section extending through the lowermost wheels of opposite series; and a Fig. 5 is a detail top plan view of one of the wheel supporting plates and the parts carried by the same.

Referring more particularly to the drawings in which similar reference characters designate corresponding parts throughout the several views, 1 designates the pulp containing tank which receives a continuous supply of pulp from a feed pipe 3 having its discharge end directed toward the open upper end of said pulp containing tank 1.

In this application as in our previously referred to original application Serial Number 7411, and also in our second and copending application Serial Number 2051,

' We employ a stationary shaft 1, extended 1. The receptable 6 is extended upwardly from the edge of the opening 5 in the bottom of the tank 1 and is spaced from the stationary shaft 4, and it will be understood that this receptable 6 may be of any suitable or well known construction. it will also be understood that the forms or former-sections A should include outer screens 20 and interior central guide nuts 9 for movement over the spirally extended feed and guide thread 8, as clearly shown in the drawings, and should be adapted to be securely locked together by some suitable and well known means (not shown). The remainder of the forms or former-sections A may be of the construction shown and described in our original and co-pending application Serial Number 741 or of any other construction, as described, and therefore further detailed description of the forms or former-sections A, in this application is believed to be unnecessary. It is also believed to be unnecessary to show or describe in this application, any means for rotating the forms or formersections A, as they may be operated by the sectional former rotating mechanism disclosed in said application Serial Number 7 11 or by any other suitable means.

I11 the present invention we employ pulp gathering and transferring wheels 21, arranged in substantially vertical series and provided with perforated peripheries, around which are secured the screens 22, for gathering pulp from the pulp containing tank 1 and transferring said pulp to the moving forms or former-sections A and partially compressing the same upon said forms or former-sections A.

The wheels 21 are arranged in substantially vertical series, to opposite sides of the forms or former-sections A, and each wheel 21 rests upon a supporting plate 23 and rotates upon a stub shaft 24; projecting upwardly from the center of the plate upon which said wheel rests. Each plate 23 has an arcuate shoe or upstanding flange 25, on its upper face and adjacent its inner edge, but inwardly of the perforated periphery of the wheel 21, to prevent liquid from passing through said perforated periphery and the screen 22 around the same, when opposite the forms or former-sections A, so that the pulp gathered upon the screen 22 of the wheel 21 may at this time be readily transferred to the screens 20 of the forms'or former-sections A. The liquid from the pulp may, however, readily pass through the screen 22 and the perforated periphery of the wheel 21 to the interior of said wheel 21, while the pulp is being gathered upon said screen 22 of said wheel 21, and then pass downwardly through the drain opening 26 in the snpportingplate 23.

Each supporting plate 23 has a tapered extended end, with which is formed an upwardly directed bearing sleeve 27, the main or body portion of said bearing sleeve 27 being connected with the upper face of the supporting plate 23 by means of a bracing and strengthening rib 28. The bearing sleeves 27 of each series are loosely mounted upon an inclined stationary bearing shaft 29, which hasits lower end secured in the socket 30 at the free or outer end of the bracket arm 31, projecting from the side of the hollow supporting member 32, upon the inclined top 33 of which rests the lowermost supporting plate 23 of the series. clined top 33 is provided with a drain opening 3% registering with the drain opening 26 of the supporting plates 23, and the hollow supporting member 32 is provided with an annular outwardly directed flange 35 around its lower edge, which is secured in some suitable and well known manner upon the upper face of the bottom of the pulp containing tank 1, around the drain opening 3% in said bottom. It will be readily seen that the drain opening 34 serves as the outlet for all liquid draining into the hollow supporting member 32 from the interior of all the wheels 21 above the same.

The supporting plates 23 and the wheels 21 are positioned on an angle corresponding to the spiral movement of the forms or former-sections A and each wheel 21 pref erably includes a central hub 36 depending from its upper face or web and removably engaged upon the stub shaft 24 provided for the same, so that the wheels 21 may be readily placed in position or removed as desired.

The bracket arms 31 are preferably extended from the low sides of the hollow supporting members 32 and the stationary bearing shafts inclined away from the same. This places the supporting plates 23 with their tapered extended ends positioned downwardly, thereby throwing the weight of the supporting plates 23 and the wheels 21 upon the bearing sleeves 27 and the sta tionary bearing shafts 29. The strain upon the bearing sleeves 27 and the stationary bearing shafts 29 is somewhat relieved, however, by permitting each supporting plate 23 to rest lightly upon the wheel 21 immediately beneath the same.

The inspring Each helical spring 37 has one incense By referring to Fig.2 of the drawings, it will be'seenthat the stationary bearing shafts 29 as well as the bearing sleeves 27, are arranged at equal distances within the tank 1', and resilient connection between corresponding supporting plates 28 of all of the series if formed by means of the helical endseeured in an ear 38 projecting from the large rounded end of one supporting plate 23, outwardly of the stub shaft at of the latter, while the opposite end of said helical spring 37 is mounted upon aibearing post 39 proj eeting-upwardly from the tapered extended end of the corres ondin su orting plate 23 of one of the adjacent series,

along the adjacent edge of said supporting plate 23 and a short distance from the bearing sleeve 27. It will therefore be evident that all of the pulp gathering and trans-- ferring wheels 21 will beat all times resiliently retained in operative position and at equal distances from the moving forms or former-sections A to assure an even and equal deposit of pulp upon all portions of the outer faces or screens 20 of the moving forms or former-sections A and a uniform compression of: the pulp by said pulp gathering and transferring wheels 21 to squeeze practically all liquid from said pulp and dry and shape the latter around said forms or former-sections A.

It is believed that the operation of gathering the pulp and transferring the same to the moving forms or former-sections A by means of the pulp gathering and transferring wheels 21, may be readily understood, upon a reading of the foregoing paragraphs, in connectionwith the drawings of this application, especially Figs. 3-and 4. his to be remembered, however, that the pulp gathering and transferring wheel 21 and the supporting plates 23 are at all times drawn inwardly toward the upwardly and spirally moving forms or former-sections A, by means of' the helical springs 37, and rotation of said pulp gathering and transferring wheels 21 is caused by; the upward spiral movement of said forms or former-sections A. It will be apparent that the springs 37 will limit outward movement of the support ing plates 23 and pulp gathering and trans ferring wheels 21, thereby causing the latter to compress and squeeze upon the screens 20 of said moving forms or former-sections- A, the pulp transferred to the latter by said wheels 21. It will also be evident that hot air or any other suitable drying agent may be directed to the interior of the moving forms or former-sections A, by any preferred means (not shown), to assist in drying the pulp while the latter is being compressed around said forms or former-sections A, if desired.

As the complete construction and operation of this device may be readily understood from the foregoing description taken in connection with the accompanying drawings, it is believed that further detailed description is unnecessary.

While the preferred embodiment of the invention has been shown and illustrated, it will be understood that minor changes in the detailsof construction andarrangement of parts may be, made within the scope of the appended claims without departing from the spirit of the invention or sacrificing any of the advantages of the same.
